Artist's Comments

Yesterday evening i accidentally passed by the photo store next block from home just before closure. I look as usual at the second hand stuff and there was a second hand Bigma (that's the Sigma 50-500mm f4/6.3). The thing is huge (never had a 30cm long 50mm :D), mounted on a tripod and pointed to the sky it looks like a telescope, but the range amplitude is simply mindboggling. The biggest flaw is the aperture, its quite dark, with no image stabilizzation, basically useless in the evenings but a pleasure to use when there's some light or when you're looking at bright stuff. Got home and decided to test it right away on something small and far away :D.

soooo big- I mean the Moon.
but also your new lens.30cm long would be too much for me-I couldn't carry it in my hands.I've got Sigma about 16 cm long and without stabilization ant it's too havy for me.so imagine 30 cm!

eheh that's 30cm when closed down, if you zoom to the max it becomes a good 15-20cm longer :D

Is that telescope a refractor or reflector?

mmmh, i have no idea what a refractor or reflector telescope is (though i guess it all depends on whether it uses a mirror to gain some additional length or just pass-through lenses, am i right?)

In this case it's not a telescope but a standard lens (albeit a long one)

Ok, you know there is two types of telescopes. A tube-shaped and a cylinder-shaped.

The tube shaped (when the light passes through one objective lens directly to the focal plane) is a refractor.

The cylinder shaped (when the light first passes through a primary mirror, and then a smaller mirror points the light into the focal plane) is a reflector.

Something like that, I suppose.
